Embodiment Construction

[0008] The present invention will be further explained below in combination with specific embodiments.

[0009] A piston ring accessory for automobiles, comprising a piston metal ring and a molybdenum coating on the metal ring, characterized in that: a number of microgrooves are arranged on the metal ring between the metal ring and the molybdenum coating, Alumina particles are arranged in the microgrooves.

[0010] The piston ring fittings for automobiles of the present invention are provided with several microgrooves on the metal ring between the common metal ring and the molybdenum coating, and aluminum oxide particles are arranged in the microgrooves. After testing, the piston ring can be reduced like this. The wear of the ring effectively prolongs the life of the piston.

[0011] The piston ring accessory for automobiles of the present invention has a simple structure, and adopts that some microgrooves are arranged on the metal ring between the common metal ring and the m...

Abstract

The invention discloses a piston ring accessory for an automobile, which comprises a piston metal ring and a molybdenum-plated layer arranged on the metal ring, wherein a plurality of microgrooves are arranged on a metal ring between the piston metal ring and the molybdenum-plated layer, and alumina particles are arranged in the microgrooves. According to the piston ring accessory for the automobile, the structure is simple, the structures that the plurality of microgrooves are arranged on the metal ring between the common metal ring and the molybdenum-plated layer and the alumina particles are arranged in the microgrooves are adopted, and therefore proved by tests, the abrasion to the piston ring can be reduced, the life of a piston is effectively prolonged, and the using requirements can be met.

Description

technical field [0001] The invention relates to an automobile accessory, in particular to a piston ring accessory for an automobile. Background technique [0002] At present, the piston ring commonly used in automobiles adopts a metal layer substrate as a structure, and a performance layer is plated on the metal layer substrate, such as a molybdenum coating layer, a nitride layer, and the like. This common structural form can meet the output requirements of the engine in a certain range, but with the rapid development of the automobile industry, the output torque of the engine is getting larger and larger, and the piston ring of this structural form gradually shows some abnormalities. The shortcomings of adaptation, such as short life, easy to pull cylinders, etc. Contents of the invention [0003] Purpose of the invention: In view of the deficiencies in the prior art, the purpose of the invention is to provide a piston ring accessory for automobiles, so that it has the a...
